How to Take Accurate Measurements

For the most accurate blood pressure measurement:

• Sit comfortably on a chair. Rest your arm on the table. Do not cross your legs. Keep your feet on the floor and straighten your back.
• Relax for about five to ten minutes before measurement.
• Place the center of the cuff at the same level as your heart.
• Remain still and keep quiet during measurement.
  ☐ Do not measure right after physical exercise or a bath. Rest for twenty or thirty minutes before taking the measurement.
• Try to measure your blood pressure at the same time every day.

Measurement

During measurement, it is normal for the cuff to feel very tight. (Do not be alarmed).

After Measurement

After measurement, press the START button to turn the device off.

Remove the cuff and record your data.

Measurements

Before measurement, refer to the section "Notes for Proper Measurement" on page 14.

Normal Measurement

Measurement with the Desired Systolic Pressure

The UA-767NFC is designed to detect the pulse and to inflate the cuff to a systolic pressure level automatically.

Use this method when re-inflation occurs repeatedly or when the results are not displayed even if the pressure decreases to 20 mmHg or less.

When the memory setting is 0:

1. Place the cuff on the arm (preferably the left arm).
2. Press and hold the START button until a number about 30 to 40 mmHg higher than your expected systolic pressure appears.
3. When the desired number is reached, release the START button to start measurement. Continue to measure your blood pressure as described on the previous page.

When the memory setting is 100:

1. Place the cuff on the arm (preferably the left arm).
2. Press the START button. All of the display segments are displayed. Zero (0) is displayed blinking briefly.
3. Press and hold the START button until a number about 30 to 40 mmHg higher than your expected systolic pressure appears.
4. When the desired number is reached, release the START button to start measurement. Continue to measure your blood pressure as described on the previous page.

Notes for Accurate Measurement

Sit down in a comfortable position. Place your arm on a table with your palm facing upward and the cuff at the same level as your heart.
☐ Relax for about five to ten minutes before taking a measurement. If you are excited or depressed by emotional stress, the measurement will reflect this stress as a higher (or lower) than normal blood pressure reading and the pulse reading will usually be faster than normal.
☐ An individual's blood pressure varies constantly, depending on what you are doing and what you have eaten. What you drink can have a very strong and rapid effect on your blood pressure.
☐ This device bases its measurements on the heartbeat. If you have a very weak or irregular heartbeat, the device may have difficulty determining your blood pressure.
- Should the device detect a condition that is abnormal, it will stop the measurement and display an error symbol. Refer to page 6 for the description of symbols.
☐ This blood pressure monitor is intended for use by adults only. Consult with your physician before using this device on a child. A child should not use this device unattended.

Caution on Using the NFC Function

The UA-767NFC has an NFC Forum Type 3 Tag wireless interface module built in. When the device is used near wireless communication devices which use the same frequency as that of the device (13.56 MHz) or use its harmonic frequencies, electromagnetic interference may occur. In that case, turn off the devices that are not in use, or place the device 1 meter or more away from the devices.

What is an Irregular Heartbeat

The UA-767NFC provides a blood pressure and pulse rate measurement even when an irregular heartbeat occurs. An irregular heartbeat is defined as a heartbeat that varies by 25% from the average of all heartbeats during the blood pressure measurement. It is important that you are relaxed, remain still and do not talk during measurements.

Note: We recommend contacting your physician if you see this “(♡)” symbol frequently.

Pressure Bar Indicator

The indicator monitors the progress of pressure during measurement.

About Blood Pressure

What is Blood Pressure?

Blood pressure is the force exerted by blood against the walls of the arteries. Systolic pressure occurs when the heart contracts. Diastolic pressure occurs when the heart expands. Blood pressure is measured in millimeters of mercury (mmHg). One's natural blood pressure is represented by the fundamental pressure, which is measured first thing in the morning while one is still at rest and before eating.

About Blood Pressure

What is Hypertension and How is it Controlled?

Hypertension, an abnormally high arterial blood pressure, if left unattended, can cause many health problems including stroke and heart attack. Hypertension can be controlled by altering lifestyle, avoiding stress, and with medication under a doctor's supervision.

To prevent hypertension or keep it under control:

☐ Do not smoke Exercise regularly
- Reduce salt and fat intake Have regular physical checkups
- Maintain proper weight

Why Measure Blood Pressure At Home?

Blood pressure measured at a clinic or doctor's office may cause apprehension and can produce an elevated reading, 25 to 30 mmHg higher than that measured at home. Home measurement reduces the effects of outside influences on blood pressure readings, supplements the doctor's readings and provides a more accurate, complete blood pressure history.

WHO Blood Pressure Classification

Standards to assess high blood pressure, without regard to age, have been established by the World Health Organization (WHO), as shown in the chart.

Reference Material: Journal of Hypertension 1999, Vol 17 No.2

Blood Pressure Variations

An individual's blood pressure varies greatly on a daily and seasonal basis. It may vary by 30 to 50mmHg due to various conditions during the day. In hypertensive individuals, variations are even more pronounced. Normally, the blood pressure rises while at work or play and falls to its lowest levels during sleep. So, do not be overly concerned by the results of one measurement.

Take measurements at the same time

every day using the procedure described in this manual to get to know your normal blood pressure. Regular readings give a more comprehensive blood pressure history. Be sure to note the date and time when recording your blood pressure. Consult your doctor to interpret your blood pressure data.

Troubleshooting
